| Abstract: | A temperature density conductivity method is proposed for the on line real time concentration measurement of sodium aluminate solution. According to the principle of the perpendicular recursive experimental design,a mathematical model,which describes the relationship between the concentration,the temperature of sodium aluminate solution and its density and conductivity,is established. This model is a non linear dualistic quadratic equation. When it is applied on the plant floor,the temperature,the density and the conductivity of sodium aluminate solution need to be measured. The measurement value is processed by a computer and the chemical concentration is then calculated. The principle of the method,the measuring system and the measurement result are presented. |
